While arguable being convenient, this is behaviour goes against the Stack api.

Some commands, such as push and pop, can be applied on stacks by passing the
stack's componentId.
This commit also fixes those stack commands which were always applied on parent stacks.

* Refactored modals

* Added unit tests for modals

* fixes unknown modal dismissing and added tests

* [V2] Added sideMenu style options similar to V1 options

* Added appropriate header import

* Documented iOS specific styling for new options

* Removed trailing commas for styling consistency

When saving buttons by screen, buttons were stored in a HashMap which doesn't maintain
order.
Closes #3916

This prevents a rare bug where the title would be styled as a button if both contained the same text

Closes #3894

when compileSdkVersion is 25, below error was occured in react native 0.56.0.
"No resource found that matches the given name: attr 'android:keyboardNavigationCluster'"
so i have to change compileSdkVersion to 26.
Please add this push on your repository.
Thanks

Rejecting the promise is a temporary solution, Overlay should not be coupled to root.

Seems like CENTERED_TEXT_HEADER is always visible so the test was not actually checking properly if the side menu closed properly.

Added a header to the sidebar to indicate that this is the V1.1.X documentation and added a link to the V2 docs.

Child options are applied when a child appears, meaning it's attached to hierarchy.
Going over the Wix app crash logs, a few users experienced a crash where apparently
BottomTabs options were applied for a child component, and a corresponding tab wasn't found.
I'm not sure how this happens and wasn't able to reproduce the crash.

Hopefully I'll have more information in the future but for now I've added a simple check to ensure
options are applied only if a tab is found.

We should also support showingModals on Android regardless of root

Some extra help concerning a common issue that occurs with fresh install of Xcode + react native 0.56. https://github.com/react-community/create-react-native-app/issues/316#issuecomment-351371080

When fresh installing `v2` branch some time getting issues with bundling. Due to `rn-packager` cache. Normal `npm start -- --reset-cache` was not working properly. So had to reset the cache manually. Maybe its because of the start script is different from regular react native app setup

Fix an imprecise path name, and fix a meaningful typo `No Run --> Now run`.

Change `index.ios` to `index` in `AppDelegate.m`.

Fixing 404 not found

Apparently, UiImplementation doesn't like it when views disappear from hierarchy unexpectedly.
As yellow boxes are added to all ReactRootViews, we remove them from TopBar components.
When these components got unmounted, UiImplementation tried to remove the yellow box and since it
couldn't find it - it crashed.

This commit simply adds the yellow box before views are unmounted.

Stack related options are applied only if the view is visible, for now this is a reasonable fix.

This needs to be addressed for other ParentControllers as well
